working chamber in a lower or hoist'cage,

is transferred to a transversely movable waitingtray from which, when the upper or gun loading cage descends into. the work ing chamber and after the tray has been automatically movedtoits discharging position, the projectileis rammed or otherwise moved on to the projectile tray of the gun loading'cage. 7

According .to the 1 present invention the said'projectile waiting tray, which is preferably pivotally mounted 011 the lower part of the powder charge waiting tray, is so constructed and arrangedthat' wheninthe discharging position (with the hoist cage vertically above the hoist cage,*the saidprojectile waiting tray being shifted laterally as the hoist cage rises so that it then occupies a receiving position. toone sideofthe hoist cage. By these means we are able to economlze space owing to the fact that the at Vickers House,

lowered) it lies vertically or approximately movements of th e projectile waiting tray be tween the receiving and discharging posi-.:.

tions take place within a space which is not greater than that circumscribed by the walls of the hoist trunk and it is therefore possible to arrange the said waiting tray within a vertical extension of the trunk. The saving of space renders the improved apparatus particularly applicable to a multiple turret.-

The means for automatically moving the waiting tray to and from its discharging position may comprise an operating cam moving with the ram of the hoisting press and preferably formed on the usual cut oil cam of the ress, the said operating cam being so arranged that the hoist cage approaches the working chamber, the waiting tray will be moved to its receiving position while Specification of Letters Patent;- Patented B91331, 1918,

when ithe-cage' descends the tray will be moved to its discharging position.

In orderthat the said invention may be clearly understoodand readily carried into effect, we will describe the same more fully .withreference to the accompanying draw- Figures 1 and-2 are respectively a side elevation -and an end elevation showing a constructional form of our improved hoisting;:apparatus,-and- Fig 3 is a transverse sectionon-a larger scale of the projectile receiver shown in Figsul and 2.

A A are-the hoist cagesfor the projectile and powder charges respectively, these cages beingmounted on guide rails in the trunk B. C, C are the projectile and powder charge waiting'trays respectively. D is the hoisting press and D! the aforesaid operating cam moving'with the ram of this ress'and formed onthe cut ofl cam D In the-example shown the projectile waitingtray C is pivotally mounted at c on the lower part of the powder chargc'waiting tray C and connected bysuitable mechanism such as an amino, links 0 c and a rode to one arm'of a lever C whose other arm carriesa roller C engaging with the operating cam DC Thedraivings show in full lines the waiting'tray C in the discharging position with the hoist cages A, A" at the lower end of the trunk B.- When the ramcf the hoisting press D moves downward in raising the hoist cages, the -cam D angularly displaces the lever. C in a clockwise direction and thereby moves the projectile waiting tray G into its receiving position indicated by chain lines in'Fig. 2. This position is such that when thecageA reaches'its uppermost position (also indicated byv chain lines) the projectile can be caused by any suitable means to roll on to the tray C. During the descent of the cage the tray C is caused by the cam D to resume its original position shown by full line-s, in which position the projectile can be transferred by means of a rammer to the projectile tray of the gun loading cage which to avoid confusion is not shown in the drawings.

What we claim and desire to secure by Letters Patent of the United States is 1. In ammunition hoisting apparatus, the combination with the projectile hoist cage, of a movable projectile waiting traydisposed approximately vertically ,above the hoist cage when the latter is lowered, and

means for moving said waiting tray so that it occup1es a recelving position to one SlCiB of the hoist cage when the latter is in its raised position.

2. In ammunition hoisting apparatus, the combination with the projectile hoist cage, of a movable projectile waiting tray disposed approximately vertically above the hoist cage when the latter is lowered, and means for moving said waiting tray so tnat it occupies a receiving position at theinner' side of the hoist cage when the latter isin its raised position.

- 3. In ammunition hoisting apparatus, thecombination with the projectile hoist cage, of a movable projectile waiting tray disposed approximately vertically above the hoist cage when the latter is lowered, and

means for automatically moving said waiting tray as the hoist cage is being raised so that said tray then occupies a receiving position to one side of the hoist cage when the latter is in its raised position.-
